The space around a keyboard and mouse is easy to lose a little at a time. A notebook pushes the keyboard sideways, a phone stand narrows the mouse area, and the monitor base stops everything from moving back. You may adapt by reaching farther or holding your arms differently without noticing why.

A comfortable input area begins with enough room for both hands to work naturally. Clear the nearby surface before evaluating the equipment itself. OSHA's keyboard guidance considers the keyboard, pointing device, chair, and work surface together; changing one accessory alone is not an injury-prevention guarantee.

Center the part of the keyboard you use

The geometric center of a full-size keyboard includes its number pad. For long writing sessions, the letter keys may be the more useful reference. Position that typing area in front of you and check where the mouse ends up.

If the mouse is far to the side, consider whether the number pad is used often enough to justify that arrangement. A more compact keyboard can reduce the span, but first try repositioning what you already own.

People who enter numbers frequently may make a different choice. The right layout depends on the task that occupies your hands, not on whether the keyboard lines up perfectly with the monitor stand.

Give the mouse a complete working area

Move the pointer across the screen and back using your normal technique. Watch whether the mouse hits the keyboard, a mat edge, or an object on the desk. It should have room to move without repeated collisions.

Adjust pointer speed if crossing the screen requires more movement than you comfortably have available. Make small changes and test precise work such as selecting text or using a spreadsheet. A fast pointer that is hard to control creates another problem.

Keep the mouse close enough that you do not reach outward with every movement. If you use a trackpad or another pointing device, apply the same test: it should be accessible without forcing your arm around an obstacle.

Check the front edge and keyboard angle

Notice where your hands and forearms contact the desk. A sharp edge can be uncomfortable even when the rest of the layout is reasonable. Moving the keyboard slightly may change where that contact happens.

Try the keyboard with its rear feet folded down if the current angle makes your wrists bend upward. There is no need to use the highest available tilt simply because the keyboard provides it.

If you use a palm support, check its height relative to the keys. It should not force your hands into a steep angle or become a hard surface you press into while typing. Support during pauses should feel different from pinning your wrists in place.

Prevent neighboring tools from creeping back

Mark out the functional area by using it, not by drawing a perfect rectangle. Leave the mouse's travel space empty and put your notebook where it will not gradually displace the keyboard.

A phone can sit farther away if you rarely touch it during work. A frequently used pen can live beside the notebook rather than between the two input devices. These small choices preserve room where your hands need it most.

After a normal work session, look at what moved. If you repeatedly drag the keyboard toward you or shove the mouse pad aside, the starting arrangement is probably wrong. Adjust it based on that evidence.

Comfort also depends on movement and time away from repeated input. Change activities when you can and take brief pauses. If pain or numbness continues, get appropriate professional guidance instead of assuming a new accessory will resolve it. The desk layout should make ordinary hand movement easier, not require you to maintain a carefully rehearsed pose.
